Suppose that you are testing the hypotheses H0: muequals18 vs. HA: mugreater than18. A sample of size 16 results in a sample mean of 18.5 and a sample standard deviation of 2.3. a) What is the standard error of the mean? b) What is the critical value of t* for a 90% confidence interval? c) Construct a 90% confidence interval for mu. d) Based on the confidence interval, at alphaequals0.05 can you reject H0? Explain. a) The standard error of the mean is nothing. (Type an integer or a decimal.)
